Cover a house made of aerated concrete with your own hands, or rent a construction company? What is the best aerated concrete for building a house? Common mistakes when building houses with aerated concrete. The rules of bandage blocks. The technology of connecting walls. The technology of reinforcing walls with aerated concrete. How to ensure the high performance of houses with aerated concrete blocks? How is the water vapor permeability of aerated concrete reflected in the selection of insulation materials? Can I use mortar instead of glue for improper reinforcement?
An article covers a wide range of topics on how to build houses with aerated concrete. Therefore, you can learn more Sapelo Island about the characteristics of materials, finishing technology, heat insulation technology and other work in our library separately. Here we will discuss general terms of architecture and focus on the main points. Cover a house made of aerated concrete with your own hands, or rent a construction company? The correct answer to this question does not depend on whether you want to use aerated concrete, bricks, wood or other wall materials to build the house.
And any house is composed of many other equally important elements (foundation, floor, roof, etc.). You must also train yourself very carefully when installing these elements, or you must choose a contractor for construction responsibly.
Like other wall materials, houses made of aerated concrete also have their advantages and disadvantages, technical and design features, which must be understood and considered during the construction process. Ignoring them can lead to hidden, long-term, complex, or generally irreparable problems, which in the future will be the cause of negative feedback from owners on houses made of aerated concrete. This is the misinformation of other consumers who only choose wall materials to build their future houses.
To independently study the biggest professional information on this topic, you need to learn architectural technology anyway. The problem is only the depth of learning and the amount of memory. The solution to this problem is not based on the selected wall materials, but on whether it is possible and willing to spend all personal time and regularly leaving the main work on the construction site. We do not consider using non-high-pressure aerated concrete for building houses at all-this is a narrow-purpose material and must not be used in future houses.
Fundamentally divide the brand and density of manufacturing plants (indicated by letters). Each of them has a specific set of physical and technical characteristics, and you need to focus on these characteristics when deciding which aerated concrete to choose to build a house.
The most common mistake related to illiteracy is the binding of the number of floors of buildings to the density of blocks. For example, you can often hear such sounds. Especially on this issue, you should only be interested in the compressive strength of the material, because the density is actually its weight and never affects the strength. This is a pattern, but it can also lead to wrong thinking in the future.
Sometimes, even if the products of the same manufacturer have the same density, their physical and mechanical properties will be very different. For example, there are many factories on the market, and on the other hand, there are many factories whose compressive strength of 501 differs by 2 (!) times, not to mention other indicators. Same with other levels of gravity and other plants.
These are building elements that you will never replace. Therefore, we strongly recommend that you use the best materials. 
After understanding the main mistakes made by amateurs or unscrupulous performers, you can build a house out of aerated concrete, which is characterized by increased reliability and durability.
If you decide to build a house with aerated concrete with your own hands, you need to understand the rules of chain link blocks. After all, the qualitative redistribution of bending and shear loads affecting the masonry during operation depends on this. Start from the height of the wall material, but it should not be less than 101 mm. When using materials whose height exceeds 251 -0.2 (21%).
And the load difference on them does not exceed 31%.
Allows deformation, so it is used when connecting walls with different loads (with a difference of 31% or more).
A serious mistake is to rigidly connect walls with different loads together-for example, using steel bars to connect load-bearing walls to curtain walls.
To build reliable and durable aerated concrete houses, you need to understand the technology of structural wall reinforcement. When using freshly made bricks, prevent shrinkage cracks-the wall material gradually dries out and reduces the humidity from 36% to 5%. Therefore, the house made of this kind of aerated concrete will shrink and last for 2 years, about 0.3 .
Traditionally, horizontal reinforcement is carried out using corrugated steel reinforcement with a cross section of 6-8. It is buried in a pre-prepared groove and fixed with an adhesive for masonry. Smooth reinforcement is not used for reinforcement. Strengthen the structure to withstand lateral loads (freestanding and underground walls, structures in areas where seismic activity increases or avalanches occur, etc.)
Many people ask the question: Can a house be constructed of low-density (and different strength) aerated concrete with lower thermal conductivity, which belongs to the insulation category. Allowed, but according to specific conditions, vertical reinforcement is required to increase the load-bearing capacity of the wall. It can also be done with metal reinforcements with variable profiles but at least 15 in diameter. The drill rod is placed in a special profile or in a hole made by yourself with a 121-151 mm core drill. In this case, the distance from the wall and the free end of the opening should not exceed 611 mm. How to ensure the high performance of aerated concrete block houses?
How is the water vapor permeability of aerated concrete reflected in the selection of insulation materials? Compared with the previous one, the one closer to the street should have higher vapor permeability. Otherwise, the excess water will not be removed from the house, as a result the walls will gradually become wet and the heat insulation effect will be greatly reduced. Therefore, if you want to build a house with aerated concrete for permanent residence (heating), you cannot use extruded polystyrene foam with almost zero vapor permeability as a heater. Brick cladding without ventilation gaps (near the wall) will also seriously affect the thermal efficiency of the building. The air gap is mandatory and should be approximately 41.
The height of the masonry is at least 2/3 of the width, so jumpers are not allowed. Reinforcing the row above the opening horizontally or using two metal corners is sufficient. There is no need to insulate existing aerated concrete doors, which can be used to close openings up to 2.5 in width.
You should also understand and remember that it is permissible to build load-bearing walls up to 11 height from bricks with a strength of 2.5, so even if you plan to use your own hands to build a two-story house with aerated concrete, you do not need a reinforced concrete structure. Such a frame significantly reduces the insulation of the wall.
But in fact, in most cases, the opening is closed with cast reinforced concrete lintels. This structure must be insulated from the outside.
From a technical point of view, traditional cement-based mortar can be used to build houses from aerated concrete. This will not affect the service life of the building, but it will increase the thermal conductivity of the wall by 26-31%, and saving glue will result in additional heating costs.
On average, the thickness of the glue line should be 3, but the best value is indicated by the manufacturer on the glue package. Vertical joints cannot be blown through, so when laying aerated concrete with smooth edges, the joints will be completely filled. When using wall materials with shaped ends (slot-comb system), it is not allowed to apply glue on the ends of the blocks, but if necessary, fill them along the entire height and width-not less than 41% (along the edges) .
Need to give him time to hurry, and then cut with a trowel or spatula. The composition is not allowed to be applied to the surface of the brick-this will reduce the total vapor permeability of the wall.
This will prevent the moisture contained in the monolithic reinforced concrete from being sucked into the aerated concrete wall by capillary action. 
When laying the first row of blocks, please carefully control the horizontal and vertical levels, the corners of the inner and outer walls and the geometry of the supports.
Install the door at the opening and fill it with cement mortar. At this stage, concrete is also poured on the internal stairs (if any).
Floor installations are usually prefabricated from reinforced concrete slabs or wooden floors.
